[0058] S101, obtaining parameter information of a crystal oscillator, wherein the parameter information includes raw material information, performance information and production information;

[0059] S102, encoding according to the raw material information and a first encoding rule to obtain a first point code, where the first point code is located in a first area 100 of the crystal oscillator;

[0060] S103, encoding according to the performance information and the second encoding rule to obtain a first character code and / or a second dot code 500, wherein the first character code and / or the second dot code 500 is located in a second area of ​​the crystal oscillator;

[0061] S104, encoding is performed according to the production information and a third encoding rule to obtain a second character code 400, where the second character code 400 is located in a third area of ​​the crystal oscillator.

[0062] It is worth noting that the crystal oscillator coding of the embodiment of the present invention is to print the coding on the crystal oscillator, so that the crystal oscillator has corresponding dot codes and character codes. The encodable area of ​​the crystal oscillator in the embodiment of the present invention is less than 2 square millimeters, and the use of a two-dimensional code cannot carry the numbering information in this encoding area at a low cost. The crystal oscillator number (that is, the raw material information) is indicated by engraving the dot code in the encodable area. The crystal oscillator number is the unique serial number of the crystal oscillator, and the crystal oscillator number of hundreds of billions or trillions can be indicated by the dot code. Some specific performance information of the crystal oscillator, such as the center frequency, load temperature, etc., is indicated by characters or dot codes, which are not specifically limited. The production information of the crystal oscillator, such as the production batch number, production date, etc., is indicated by other characters, which are not specifically limited.

[0063] It should be noted that the embodiment of the present invention can store the parameter information of the crystal oscillator by encoding when the crystal oscillator is produced. When the parameter information of the crystal oscillator needs to be obtained, only the corresponding code needs to be scanned and identified to obtain the specific parameter information, and there is no need to retest and obtain, which is convenient and fast, and simple to maintain. Specifically, the raw material information (that is, the number of the crystal oscillator) in the obtained parameter information is encoded to obtain the first dot code, and the first dot code is used to mark the unique serial number of the crystal oscillator. The specific dot code can be a dot code of different shapes, or a dot code of the same shape with different colors, or a dot code of different shapes plus different colors, which is not limited here. The first dot code is engraved / pasted on the first area 100 of the crystal oscillator, and the number of the crystal oscillator can be obtained by identifying and decoding the first area 100. The performance information of the crystal oscillator, such as the center frequency, load temperature, and load capacitance, is represented by the first character code and / or the second dot code 500, and the first character code and / or the second dot code 500 is printed / pasted on the second area of ​​the crystal oscillator. Specifically, the first character code includes letters, numbers, symbols, etc., which are not specifically limited; the second dot code 500 can be a dot code of different shapes, or a dot code of the same shape with different colors, or a dot code of different shapes plus different colors, which are not specifically limited here. The production information of the crystal oscillator is encoded to obtain the second character code 400, and the second character code 400 is printed / pasted on the third area of ​​the crystal oscillator. The specific production information includes the production batch number, the production date, etc., and the specific second character code 400 includes letters, numbers, symbols, etc., which are not specifically limited. When it is necessary to obtain specific parameter information, it is only necessary to scan and identify the codes of the first area 100, the second area, and the third area. The crystal oscillator parameter information can be quickly obtained without removing the crystal oscillator. The crystal oscillator parameter information is easy to obtain, and the crystal oscillator maintenance cost is low.

[0064] In some optional embodiments, Figure 1 The step 102 shown includes but is not limited to: encoding according to the raw material information and the first coding rule to obtain the first point code, including: obtaining the base plate serial number and the crystal oscillator base sequence number of the crystal oscillator according to the raw material information, the base plate serial number represents the serial number of the base plate of the crystal oscillator when the raw materials are put into storage, and the crystal oscillator base sequence number represents the position of the crystal oscillator on the base plate; encoding the base plate serial number to obtain a base plate ID code, and the base plate ID code is a first type of point code; encoding the crystal oscillator base sequence number to obtain a crystal oscillator position code, and the crystal oscillator position code is a second type of point code, and the base plate ID code and the crystal oscillator position code are arranged in sequence to obtain the first point code.

[0065] Specifically, the raw material information (i.e., the crystal oscillator number) is composed of the base plate serial number of the crystal oscillator and the crystal oscillator base sequence number. The first point code is obtained by encoding the base plate serial number and the crystal oscillator base sequence number. The base plate serial number is the number of the base plate where the crystal oscillator is located (i.e., the serial number of the base plate when the raw materials are put into storage). It can be specifically represented by a thirty-point point code, that is, the base plate serial number is encoded to obtain the base plate ID code. The specific number of point codes is set according to demand. The base plate ID code is a first type of point code. The first type of point code can be a point code of different shapes, or a point code of the same shape with different colors, or a point code of different shapes plus different colors. There is no specific limitation. The crystal oscillator base sequence number indicates the position of the crystal oscillator on the base plate. Specifically, a base plate includes multiple crystal oscillators, and the specific number is not limited. In this implementation, the crystal oscillator base sequence number is represented by an eight-point code, and the representation range is 0-255, that is, the crystal oscillator base sequence number is encoded to obtain a crystal oscillator position code. The crystal oscillator position code is a second type of point code. The second type of point code can be a point code of different shapes, or a point code of the same shape with different colors, or a point code of different shapes plus different colors, which is not specifically limited. The base plate ID code and the crystal oscillator position code are arranged end to end to obtain the first point code.

[0066] In some optional embodiments, encoding the base plate serial number to obtain the base plate ID code includes: converting the base plate serial number into a binary code to obtain a base plate binary code; and matching the base plate binary code with a point code one by one to obtain the base plate ID code, wherein the one-to-one correspondence represents the correspondence between a binary code and a point code.

[0067] Specifically, the base plate serial number is converted into a binary code, that is, the base plate serial number is represented by a binary code to obtain the corresponding base plate binary code, and the corresponding number of dot codes is determined according to the number of bits of the binary code; the dot code can specifically represent binary "0" and "1" through different shapes, or can represent binary "0" and "1" through different colors, or can represent binary "0" and "1" through different shapes and different colors, or can represent binary "0" and "1" with blank dot codes and non-blank dot codes, and the specific representation method is not limited here.

[0068] In some optional embodiments, the base plate ID code and the crystal oscillator position code are arranged in sequence to obtain the first point code, including: adding a first direction marking point code 110 at the starting position of the base plate ID code, the first direction marking point code 110 indicates the starting position and the first arrangement direction of the base plate ID code; setting a plurality of second direction marking point codes in the corner area of ​​the first area 100, the second direction marking point code indicates the second arrangement direction of the base plate ID code and the crystal oscillator position code after the corner; the base plate ID code and the crystal oscillator position code are arranged in sequence under the indication of the first direction marking point code 110 and the second direction marking point code to obtain the first point code, the first point code includes the first direction marking point code 110, the second direction marking point code, the base plate ID code and the crystal oscillator position code.

[0069] Specifically, the first direction mark point code 110 is added to the starting position of the base plate ID code, that is, the starting position and arrangement direction of the base plate ID code are marked by the first direction mark point code 110. Figure 2 The first direction mark point code 110 is set to two point codes, which can be point codes of different shapes or colors. The arrangement direction of the base plate ID code is indicated according to the arrangement direction of the two point codes. After the base plate ID code is arranged at the corner, the corner direction is indicated by the first mark 122 in the second direction mark point code, the arrangement direction is indicated by the third mark 123, and the corner direction after another corner is indicated by the second mark 121, and the arrangement direction is indicated by the third mark 123 again; the base plate ID code and the crystal oscillator position code are connected end to end and arranged in sequence.

[0070] In some optional embodiments, the first point code also includes a CRC code, and the method further includes: arranging the CRC codes in sequence at the end position of the crystal oscillator position code; adding an end mark point code 130 at the end position of the CRC code, the end mark point code 130 indicates the stop of arranging point codes, and the end mark point code 130 belongs to the first point code.

[0071] Specifically, the CRC (Cyclic Redundancy Check) code is set after the crystal oscillator position code, and is arranged from the end position of the crystal oscillator position code to obtain the CRC code. The specific CRC code is a ten-point code, which is not limited. An end mark point code 130 is added to the end position of the CRC code to indicate that the point code arrangement stops. When scanning and identifying the point code, the scanning and identification stops at the end mark point code 130.

[0072] In some optional embodiments, from Figure 2There are 48 marking positions, starting from the black dot in the upper left corner and ending with the black dot in the lower right corner. These 48 marking positions can be marked or not. When marked, they represent binary "1", and when not marked, they represent binary "0". Or different shapes and colors can be used to represent binary "0" and "1". Figure 3 The first dot code represents binary "1" through a diamond dot code and represents binary "0" through a blank dot code, so that the crystal oscillator number and CRC value represented by the first dot code are 251971414687.

[0073] The base plate ID code is the first 0 to 29 bits of the 48-bit code, which contains the number of the base plate where the crystal oscillator is located. One base plate can produce multiple crystal oscillators.

[0074] The crystal position code is bits 30 to 37 of the 48-bit bit code, and contains the sequence number of the base plate where the crystal is located. The sequence number can be 0-255.

[0075] The CRC code is bits 38 to 47 of the 48-bit bit code, specifically including a 10-bit value obtained by CRC checking the base plate ID code and the crystal oscillator position code.

[0076] The CRC code is calculated as follows:

[0077] The initial value of the CRC code is 0, and it is calculated using the polynomial x8+x2+x1+1 (0x107).

[0078] The base board ID code and crystal oscillator position code are 38 bits in total. If we calculate every 8 bits in a cycle, 40 bits are needed, so the high bits are padded with 0s for a total of 40 bits. The base board ID code is the high bit, and the crystal oscillator position code is the low bit. For example, if the base board ID code is 0x3AAAAAAA and the crystal oscillator position code is 0x9F, then the value of the base board ID code and the crystal oscillator position code combined is 0x3AAAAAAA9F.

[0079] Starting from the lower eight bits, perform XOR processing in sequence: XOR with the CRC value, and the result of XOR determines whether the 8th bit is true. If it is true, shift it left by 1 bit and XOR it with the polynomial 0x107. If it is false, shift it left by one bit.

[0080] The executed CRC result is then XORed with the remaining 9 to 40 bits four times in sequence, and the lower 10 bits of the obtained CRC value are the CRC code.

[0081] In some optional embodiments, Figure 1The shown step 103 includes but is not limited to: converting the performance information into binary code to obtain a performance binary code; matching the performance binary code with the point code one by one to obtain the second point code 500; and / or converting the performance information into first code number information according to a first preset comparison table, the first code number information is represented by a number; converting the first code number information into the first character code according to a second preset comparison table.

[0082] Specifically, by converting the performance information such as the center frequency and load temperature into binary code according to the corresponding conversion rules, and expressing the binary code as the corresponding dot code according to the above rules, 4096 codes are obtained, which are not specifically limited. And / or according to the first preset comparison table, the performance information is converted into the first code number information, and the first code number information is represented by numbers, that is, different center frequencies and load temperatures are represented by different numbers; according to the second preset comparison table, the first code number information is converted into the first character code, so that the corresponding performance information is represented by the first character code. The specific second preset comparison table can be as follows:

[0083] Table 1 The second preset comparison table of center frequency

[0084]

[0085]

[0086] The center frequency specifically represented by each code number (character) in Table 1 is determined by the process and is not specifically limited.

[0087] Table 2 The second preset comparison table of load temperature

[0088]

[0089] The load temperature specifically represented by each code number (character) in Table 2 is determined by the process and is not specifically limited.

[0090] In some optional embodiments, Figure 1 The shown step 104 includes but is not limited to: converting the production information into second code number information according to a third preset comparison table, the second code number information is represented by a number; converting the second code number information into the second character code 400 according to a fourth preset comparison table, the value range of the first character code is a first set, the value range of the second character code 400 is a second set, and the intersection of the first set and the second set does not include an empty set.

[0091] Specifically, refer to Figure 2, the production information such as the production batch number and the production date is converted into the second code information (such as the center frequency character 200 and the load temperature character 300) by comparing with the third preset comparison table, and the second code information is represented by a number; according to the fourth preset comparison table, the second code information is converted into the second character code 400, thereby obtaining the second character code 400 engraved on the third area, and the first character code and the second character code 400 can be the same. The corresponding production information can be obtained by scanning and identifying the second character code 400. The specific fourth preset comparison table can be as follows:

[0092] Table 3 The fourth preset comparison table of factory batch numbers

[0093]

[0094] The factory batch number represented by each code number (character) in Table 3 is determined by the process and is not specifically limited.

[0095] In some optional embodiments, the second dot code 500 is a 4096 code, which is a 12-bit binary number composed of 3 times 4 dot codes, all of which are valid, and does not include direction and CRC check. It actually represents the combination of center frequency and load temperature, and the center frequency and load temperature can be restored through the 4096 code.

[0096] If you need to verify its accuracy, you can use the crystal number to query whether the center frequency and load temperature in the database are the same as the parameters represented by the existing 4096 code.

[0097] The calculation method of 4096 code is as follows:

[0098] 4096 code = center frequency code number * 64 + load temperature code number;

[0099] The center frequency code number is calculated by performing a modulo operation of 4096 code to 64: center frequency code number = 4096 code / 64;

[0100] The calculation method of the load temperature code number is to perform a modulo operation of 4096 code to 64: load temperature code number = 4096 code% 64.
